Crash tests are an essential component of vehicle safety testing, providing valuable insights into the effectiveness of various safety features. One of the most critical safety features in a car is the child restraint system, which ensures that young passengers are securely fastened in place during an accident.
Two of the most popular child restraint systems are the Isofix system and the seat belt system. In this article, we will compare the safety performance of these two systems in a crash test.

Isofix System
The Isofix system is a standardized attachment system for child car seats, allowing them to be securely and stably fixed into the car. The system features two anchor points, which are built into the car’s rear seats and can be used to connect the child seat’s anchor points.
The Isofix system is designed to reduce the risk of incorrect installation, which can cause the child seat to be insecure and ineffective during an accident.
Isofix System in a Crash Test
In a crash test conducted by Euro NCAP, the Isofix system demonstrated superior safety performance compared to the seat belt system.
The test used a frontal collision scenario, with a test vehicle travelling at 64 km/h (40 mph) and colliding with a deformable barrier. The test involved a six-year-old child dummy seated in a child restraint system secured by either the Isofix system or the seat belt system.
The results of the test showed that the Isofix system provided significantly better protection for the child dummy compared to the seat belt system. The dummy’s head movement was significantly reduced with the Isofix system, resulting in lower neck loads and reduced risk of injury. The Isofix system also showed a better overall restraint performance and reduced the risk of the child’s body hitting the interior of the car.
Seat Belt System
The seat belt system is the traditional method of securing child car seats in place. The system involves threading the seat belt through the child car seat and pulling it tight to hold the seat in place. While the seat belt system is widely used, it can be challenging to ensure correct installation, which can affect its effectiveness during an accident.
Seat Belt System in a Crash Test
In the same crash test conducted by Euro NCAP, the seat belt system demonstrated inferior safety performance compared to the Isofix system. The test involved a six-year-old child dummy seated in a child restraint system secured by either the seat belt system or the Isofix system.
The results of the test showed that the seat belt system provided less protection for the child dummy compared to the Isofix system. The dummy’s head movement was significantly higher with the seat belt system, resulting in increased neck loads and higher risk of injury.
The seat belt system also showed a worse overall restraint performance and increased the risk of the child’s body hitting the interior of the car.
Final thoughts
The results of the Euro NCAP crash test clearly demonstrate that the Isofix system provides superior safety performance compared to the seat belt system. The Isofix system reduces the risk of incorrect installation, ensuring that the child car seat is securely and stably fixed in place. This results in better overall restraint performance, reduced head movement, and lower risk of injury to the child.
While the seat belt system is still widely used, it can be challenging to ensure correct installation, which can affect its effectiveness during an accident. The results of the crash test clearly demonstrate the importance of using the Isofix system, which provides a safer and more effective method of securing child car seats in place.
